MACHINE FOR ATTACHING BUTTONS TO GARMENTS.

SPECIFICATION forming part of Letters Patent No. 562,571, dated June 23, 1896.

Application filed April 14, 1892.

To all whom it may concern.-

Be it known that I, DANIEL A. CARPENTER, of New York city, in the county and State of New York, have invented a certain new and useful Improvement in Machines for Attaching Buttons to Garments, of which the follow ing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in machines which are adapted to attach buttons to garments by means of a rivet or similar metal fastening; and the invention consists of a machine having substantially the parts and combination of parts herein described and claimed.

In the accompanying sheets of drawings, Figure 1 is a side elevation of the machine with one side of the stand removed; Fig. 2, an enlarged side view, partly sectional; Fig. 3, a front elevation. Figs. 4., 5, and 6 are front views, partly sectional, illustrating the operation; Figs. 7 and 8, details of the receiver and separator; Figs. 9 and 10, views of the button and fastener.

Similar reference-numbers designate like parts in the several views.

In Letters Patent No. 525,133, dated August 28, 1894, a machine is described by means whereof button-fastenings with an ordinary tubular stem may be fed from a reservoir and inserted in garments, and buttons like those known as cone buttons maybe attached to the garments with the fastenings, this work being entirely done by the machine. The ma chine herein described is adapted to do the same work, but differs from the other machine in respect to a portion of the mechanism employed for inserting the fastening in the garment, and in that respect is an improvement upon that machine, for not only is the improved mechanism better mechanically, but it enables more space to be providedfor the garments.

The buttons and fastenings are illustrated in Figs. 9 and 10 of the drawings. The button has no opening inits face, but a central depression resembling an inverted cone, and against this cone the stem of the fastening is split and turned outward after it has been inserted in the garment, as indicated in Fig. 10.

The machine is mounted upon a standard Serial No. 129,092- (No model.)

These parts form a single casting. On the part l is bolted an arm 4, and also to the part 1 is pivoted a lever 5. Through the front portion or head 6 ofthe frame passes a button-anvil 7, which is connected with the lever 5 by a short link 8. A slide 9, shaped like a staple, is mounted on the head, the legs 10 10 of the slide being fitted in grooves in the sides of the head, and the slide is also connected with the lever 5 by a. link 11. The anvil 7 and slide 9 are therefore operated by the lever 5 and move down and back together. On the slide 9 are pivoted two cams 12 12, and these are held vertical against the legs 10 10 of the slide by a bow-spring 13, except when they are forced outward, as will presently be explained.

The head is provided with ears 14 14, on which are pivoted levers 15 15, room enough being left to allow the legs 10 10 of the slide 9 to pass between the levers 15 15 and the sides of the head. These levers are pivoted at the points 16 16, and each of them has a roller 17 at its upper end, above the pivot, and another roller 18 below the pivot. Fingers 19 19 are also pivoted on the head close to its lower end, and are connected with the levers 15 15 by links 20 20. A bow-sprin g 21, extending behind the head tends to hold up the fingers 19 19, as is shown in Figs. 2 and 3, by keeping the upper ends of the levers 15 15 against the legs 10 10 of the slide 9.

In the lower part 3 of the frame is adrivinganvil 22, and through this extends a needle 23, which is adapted to slide within the anvil. The base 24: of the anvil and the base 25 of the needle are connected with a lever 26, pivoted between the sides of the part 3, by links 27 and 28, respectively. When this anvil is in its lowest position, (indicated in Figs. 1, 2, and 3,) it rests upon the base of the needle, as shown in those figures. The link 27 is slotted near its lower end and is attached to the lever 26 farther from the pivot 29 of the lever than is the link 28, the length of the unslotted portion of the link 27, plus the distance of its lower pivot from the pivot 29 of the lever, being greater than the length of the link 28, plus the distance of its lower pivot from the pivot 29, and the difference in height between its upper pivot and that of the link 27. This arrangement enables the anvil and needle to be raised to a certain height together by the link 28, and the anvil then to be raised still higher, without the needle, by the link 27, and by means of this mechanism, in connection with the fingers 19 19 and the anvil 7, the fastening is first driven through the cloth and afterward clenched in the button. The operation is fully described below.

The levers 5 and 26 are connected bya rod or link 30, and a treadle-rod 31 connects the link with a treadle 32 at the bottom of the stand. The coil-spring 33 is intended to restore the parts to their proper positions after they have been actuated by the treadle.

On the arm 4 is mounted a reservoir 34, having openings through which the fasteners can be discharged from the reservoir, and within the reservoir is a brush, or other suitable mechanism for stirring the fasteners, which is operated from the lever 5 by means of a ratchet and pawl 35 and rod 36. A chute 37 extends downward from the reservoir nearly to the base of the frame behind the anvil 22, and on the lower end of the chute is fixed a combined receiver and separator by means of which the fasteners are fed one at a time to the anvil. The enlarged views of this device, Figs. 7 and 8, illustrate the details of its construction not shown in the other drawings. It is composed of two parts 38 and 39, which are formed into fingers 4O 41 at one end of the device, and into the receiver 42 at the opposite end. Half of the receiver is made in the part 38 and the other half in the part 39, and these are attached together to the back of the chute by a pivot 43. They are so arranged that when the receiver is closed the upper finger 41 projects partly across the channel of the chute, and when the receiver is open this finger no longer obstructs the channel, but the lower finger then projects into or over the channel. The receiver is located directly in the path of the anvil 22, and is kept closed by a bow-sprin g 44, exeepting when it is held open by the anvil in the operation of the machine. I11 the receiver is an opening 45 corresponding to the channel of the chute, that is to say, with the shape of an inverted letter T in cross-section, and through the lower part of the receiver is a hole 46 large enough to allow the needle 23 to pass freely into the stem of the fastener, but not large enough where it intercepts the opening- 45 to let the head of the fastener fall into it. The sides of the receiver around the hole 46 are beveled, as shown in Figs. 4, 5, and 6, the cavity thus formed being at the bottom of slightly greater diameter than the anvil. Above the receiver is a table 47, which has an opening in it to allow the anvil 22 to pass up through the table. A holder 48 for the buttons is attached to the frame and projects forward underneath the head (3. This holder consists of a piece of metal with an open slot at its front end adapted to receive the stem or hub of the button, and to guide the button to a point directly under the anvil '7, and is so constructed that it will descend with that anvil and return automatically to its normal position when the anvil rises.

In the operation of the machine the fasteners are fed down the chute 37 from the reservoir 34, but the buttons are placed by hand in the button-holder 48. The garment 49 is laid on the table 47. lVhen power is applied to the treadle, the levers 5 and 26 are actuated together, causing the anvil 7 and slide 9 to descend and the anvil 22 to rise. The cams 12 12 on the slide 9 strike the rollers 17 17 of the levers 15 15 and throw the upper ends of these levers outward and their lower ends inward and downward, so as to close the fingers 19 19, as indicated in Fig. 4. The fingers are thus held by the cams for a short interval while the cams are passing the rollers. In the end of each of the fingers is a semicircular notch and these notches form an opening just large enough to receive the stem of the fastening when the fingers are closed, as appears in Fig. 4. The anvil 22 is forced upward, in the first place, by the link 28, which raises the needle and with this the a11- vil, and the needle enters the stem of the fastener restingin the receiver The pressure of the anvil against the beveled sides of the cavity 46 opens the receiver and the fastener is carried upward with the needle projecting above the stem of the fastener. The needle pierces the cloth and the fastener is driven through it and through the opening in the fingers 19 19, which form a garment-rest, to resist the pressure exerted against the garment by the needle and fastener.

\Vhen the fastener has been inserted in the garment with its head or flange close to the under side thereof, the slide 9 reaches the point in its descent where the cams 12 12 cease to act on the levers 15 15, and the fingers 19 19 quickly separate and return to the positions in which they were at the beginning of the operation. This movement is ordinarily produced by the spring 21, but the legs 10 10 of the slide 9 are designed to act upon the rollers 18 18 for the purpose of separating and raising the fingers, as indicated in Figs. 5 and 6, in case the strength of the spring should not be sufficient for this work. The anvil 22 continues to move upward, carrying with it the garment with the fastener inserted therein, while the anvil 7 descends upon the button, and the fastener enters the button and is upset within it, as is shown in Fig. 6 of the drawings. The anvil 22 reaches the highest point to which it can be elevated by the link 28 before the fastener is upset. Then the needle stops and the farther upward movement of the anvil is produced by the link 27, which acts directly upon the anvil and forces this upward alone, so that the needle does not I TO strike the button or otherwise interfere with its attachment to the garment. The fingers 19 19 are only actuated by the earns 12 12 when these descend, for as the slide 9 returns to its highest position, after the button has been attached, the cams are forced to swing outward on their pivots by the rollers 17 17 acting-against the backs of the cams, while the levers 15 15 remain stationary, and as soon as the cams will clear the tops of the rollers they are pressed inward by the spring 13, and are held vertical by it against the sides of the slide as at the beginning of the operation. The cams are recessed on the back, and the lower end of the recess is inclined upward and outward, as indicated in Figs. 2 and 3, so that proper space is afforded for the rollers 17 17 when they move inward against the slide 9, after the cams have passed below them, as above described.

By opening thereceiver in the manner described, to release the rivet, the anvil 22 likewise actuates the separator connected with the receiver, throwing the upper finger ll outward and the lower one 40 inward, as

shown in Fig. 8, and when the anvil descends and the receiver closes under the action of.

the spring 44, the fingers again assume the respective positions in which they are shown in Fig. 7, and the lowest rivet then becomes free to slide down into the receiver, for use with the next button.

The receiver and separator, and the anvil 22 and needle 23 and the mechanism connected therewith, are fully described and claimed in the other application above mentioned.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
